Reconstruction of orbital exenteration defect with cheek or combined cheek and forehead advancement flaps

Abstract

Purpose: To review the outcomes of orbital exenteration defect reconstruction using cheek or combined cheek-forehead advancement flap. Methods: Charts of 14 patients who underwent reconstruction of the exenterated orbit with cheek advancement flap were reviewed. In surgery, a cheek flap elevated via a nasofacial sulcus incision, and preperiosteal dissection was advanced over the defect. The upper orbital defect, if necessary, was covered with a forehead flap, which was dissected through an incision in the midline or temporal forehead and advanced inferiorly. Results: In all patients (7 women, 7 men; mean age, 65 years), total (n = 7) or extended (n = 7) exenteration was performed for a malignant tumor. In 12 patients (86%), the defect was primarily closed with cheek flap alone (n = 6) or cheek plus forehead (n = 6) advancement flaps. Eight patients received radiotherapy before and after surgery. Four patients (29%) had a total of 6 postoperative complications (skin graft infection, orbital cavitary abscess, osteomyelitis, chronic skin ulcer, and 2 sino-orbital fistulae). The mean follow-up duration was 43 months (range, 11-79 months). Conclusions: Cheek advancement flap can be used alone or together with a forehead advancement flap to cover the orbital defects after total or extended exenteration. This repair may be resistant to radiotherapy-related complications in some cases.
